THEORY OF CREATION

Salvation
Advaitins believe that suffering is due to Maya, and only knowledge (called Jnana) of Brahman can destroy Maya. When Maya is removed, there exists ultimately no difference between the Jiva-Atman and the Brahman. Such a state of bliss when achieved while living is called Jivan mukti. While one is in the pragmatic level, one can worship God in any way and in any form, like Krishna or Ayyappa as he wishes, Adi Shankara himself was a proponent of devotional worship or Bhakti. But Adi Shankara believes that while Vedic sacrifices, puja and devotional worship can lead one in the direction of jnana, true knowledge, they cannot lead one directly to Moksha.

 Theory of creation

In the relative level, Adi Shankara believes in the Creation of the world through Satkaryavada. It is like the philosophy of Samkhya, which says that the cause is always hidden into its effect—and the effect is just a transformation of the cause. However, Samkhya believes in a sub-form of Satkaryavada called Parinamavada (evolution) — whereby the cause really becomes an effect.
                     Instead, Adi Shankara believes in a sub-form called Vivartavada. According to this, the effect is merely an apparent transformation of its cause — like illusion. e.g., In darkness, a man often confuses a rope to be a snake. But this does not mean that the rope has actually transformed into a snake.
At the pragmatic level, the universe is believed to be the creation of the Supreme Lord Ishvara. Maya is the divine magic of Ishvara, with the help of which Ishvara creates the world.
                 The serial of Creation is taken from the Upanishads. First of all, the five subtle elements (ether, air, fire, water and earth) are created from Ishvara. Ether is created by Maya. From ether, air is born. From air, fire is born. From fire, water is born. From water, earth is born. From a proportional combination of all five subtle elements, the five gross elements are created, like the gross sky, the gross fire, etc. From these gross elements, the universe and life are created. This series is exactly the opposite during destruction.
                                  Some people have criticized that these principles are against Satkaryavada. According to Satkaryavada, the cause is hidden inside the effect. How can Ishvara, whose form is spiritual, be the effect of this material world? Adi Shankara says that that just as from a conscious living human, inanimate objects like hair and nails are formed, similarly, the inanimate world is formed from the spiritual Ishvara.

Status of ethics                               
Some claim that there is no place for ethics in Advaita, because everything is ultimately illusionary. But on analysis, ethics also has a firm place in this philosophy—the same place as the world and God. Ethics, which implies doing good Karma, indirectly helps in attaining true knowledge. The traditional ethical system put forth by Advaitins is that the basis of merit and sin is the Shruti (the Vedas and the Upanishads). Truth, non-violence, service of others, pity, etc. are Dharma, and lies, violence, cheating, selfishness, greed, etc. are adharma (sin). However, no authoritative definition of Dharma was ever formulated by any of the major exponents of Advaita Vedanta. Unlike ontological and epistemological claims, there is room for significant disagreement between Advaitins on ethical issues.

The impact of Advaita

Advaita rejuvenated much of Hindu thought and also spurred debate with the two main theistic schools of Vedanta philosophy that were formalized later: Vishishtadvaita (qualified nondualism), and Dvaita (dualism). Advaita further helped to merge the old Vedic religion with popular south-Asian cults/deities, thus making a bridge between higher types of practice (such as jnana yoga) and devotional religion of simple householders
